Detailed Description

Adapter class for creating a weighted symmetric operator from an Epetra_MultiVector and Epetra_Operator.

This class will apply the operation $(WA)^T*WA$ for the Apply method of the Anasazi::Operator. The Anasazi::EpetraW2SymMvOp operator is useful when trying to compute a few singular values of the Epetra_MultiVector $ A$ under the weighting matrix $ W$ . The singular values are the square-root of the eigenvalues of .

Note: The Epetra package performs double-precision arithmetic, so the use of Epetra with Anasazi will only provide a double-precision eigensolver.
